The main overall impeller hub surface machining toolpath planning method

Integral impeller parts in the aerospace, utilities, shipbuilding industry has a wide range of uses, is the core of aviation engine parts, in the field of defense industry occupies an important position. Integral impeller is a typical complex parts, usually 5-axis NC machining method its processing, processing interference crash in serious condition. The processing area can be divided into leaf surfaces, bevel surfaces, and the hub surface. More current research as well as efficient  Diamond blade  surface finish, etc., and the hub surfaces, and surface processing methods chamfering little research. I mainly study the overall impeller hub surface machining  polycrystalline diamond  method. Overall impeller hub surfaces are a special class of surfaces, and its unique position in that it has two surfaces to determine the boundaries as constraints, and the impeller surface and perpendicular to the axis of symmetry line of intersection of a plane is a circle. The two boundary  cutting tools  is usually chamfer line of intersection of the wheel hub. Therefore, the hub surface toolpath processing methods can be handled in accordance with the channel. Notable feature of this method is the use of channel two constraints to plan its tool path curves. But the most fundamental problem is how to remain based on these two boundaries in accordance with the process for planning permission error toolpath. Introduced the principle of channel processing methods.
